To alliwhdm-ttcamera;

Be it known that I,- J; 1 Mns Romper Con; a citizen of-the-United States, :resiehng at Ansonia -countyof NeW-Haven,-State of Con 5 necticut,=have invented-certain new and use-- ful Improvements irispindles -ofwhich the 1 following is a SPEGlfiMtlOIl-P My invention relates -to yarn I spinning; or twist mpparatus-and more 'PGK'lJIOUIBiI'ly' to forms-2% such ap aratuswherein-high spindle" speed is attaine 1 The invention 1 has special reference to the construction, mounting, and lubrication of the spindlesythe =ob'e'ct being-to prevent vibration thereof, red uce rfrictlon andthe -'-re-- sulting Wear upon the moving'pa-rts and-ren dei' the same-noiselessinrunning: To'thisend, the spindle is mountedin suspended- 're-- 18|fiOI1il30*l:tS bearings and'isheld-by the same 20 in perfect '-bal-ance.-= Such an arrangementaffords many im ortant advantagesan'that it'permits' the be bins to be seated low upon the spindles and the weight thereof lto 'beefialized above and-below- -the main'bearing' 28 W ch is pref'rabl "-located'at the-u per end of the spindler n connection'wit such amounting for the spindles, provision is madefora continuousfeed and' distribution of oil on other lubricant throughout the .bearin s,

the-effect of-which is to-maintain the spin e" bearings'in anienveloping 'film of oil, and as'a' result, allffniction; noise, -etc.-is done awaywith, permittingthe spindles to be drivenat the highest possible speedwithoutvibration, heating, or'wea-r ofthe bearings;-

The accompanying drawingswill serve to i illustrate "several forms of spindles embodyin m invention.

Fig. 3-is a vertical section illustrating a modified form of-s indle, and Fig. 4-is a similar view-of a-furtgerimodificationiv Reten ing now tothe dr'awin s:- The spindlelshownconsists essentially o two-parts ormembers, 1 and 2. The member-1 is mount- 50 eel iipon the 'spindlerail' 3,' and: serves as av support for the other member, 2, in the-fo'rmof a sleeve, which is rotatably mountedthere on :with bearings at each'end=thereof.

The 'upper ormain bearing ispreferably' in ,55 the form of a ball; 4, which is seatedin a recess in the-end of. the supporting-member;- '1 and serves to hold the member 2 centered-and in susgeneled relation 'thereto: The member-2 s c sed atits upper'end; the bore thereof-be mg tapered-or coned, as indimtedat 5 to e0"- act-with the ball't- The lower bearing- 6, is preferably conical; asrshown 'in'F' 1 and 8," and combines with the 'upper'bearmg to holdthe member 2 imperfect balance andcentereda relatively to the member -1.'- The -bearings4-65' and 6 thus constitute-terminal-bearings-for the rotatable member. The 1 member- 2 is driven 'in the usual manner" by=means of i3.- whirl,"7, fast thereon,-around which asses a driving belt (not shown). The -whir serves=- as a rest'forthe bobbin 8, which seats thereon'when in osition-upon the spindle.

The spin eat-its lowcr endis mclosedlin'a: supporting 0&S6y-9,'Wl1i0h isfitted-in-an 0 air-'- ing-in the spindle rafl 3,,and secure 'by'75'- clampnut, 10 threaded upon the lower proj ecting end thereof. Above therail the cas mgis enlarged-to form 'a base ll, whieh is bored out to provide a cup -or*chamber-,'12,' suitable -forholding a quantity of oil'or.otherlubricant, 13x Ascrewcap, .14, serves'to: close-the oilcup-or chamber-in'the base and isprovide'dcentrally 1 with anopening,- 15; through which thespindleprojects.

I have shown-the helical grooveas a screw thread extending along the wall'of-therotatable member the adjaeent grooves -being-s arated merely bythescrewthi'eads' where y a substantially continuous film'ofoil separates the rotatable' member and the 1 support. ,By arran in the groove on the rotatable member t e m of oil is rotated continuously around the stationary support. An opening 23 serves to deliver 011 into the lower end of the groove and also above the conical lower bearing 6. Return for the surplus oil thus delivered is provided by way I -of a passage, 19, formed centrally of the support 1, whichleads downward from the recess therein in which the ball 4 is seated practically air tight, to exclude all forelgn matter and revent leakage.

In the modification illustrated in Fig. 3 the direction of flow of'the oil is reversed, that is to say, it is fed through the tubular portion of the support 1 to the upper end of the spindle and the surplus oil returns to the cup or chamber 12 by working its way downward through the bearings. For this purpose, there is secured centrallly within the driven member of the spind e, a rod, 21, which turns freely in the up er tubular portion of the supporting member 1. The rod 21 extends from the extreme up or end of the bearin 4 spindle, downward to the brane passages 20 olppning into the oil cup, and is provided t oughout its length wit a thread or helical groove, 18, by means of which the feed and elivery of oil to the upper bearing is effectedi Instead of employinga ball for the up or bearing of the spindle, as in Figs. 1 and 2, I have shown in this instance a cone The driving whirl is also of a somew at different type, it being shown threaded upon the member 2 and having in part with it an upturned retaining flange, 22, which forms a circular seat concentric with the spindle to receive the head of the bobbin. Otherwise, the construction is substantially the same as that above described in reference to Figs. 1 and 2.

combinedstep and bolster bearingis shownfor the driven member of the spindle and provision is accordingly made for drawing oil from a lower oint in the supporting case to include both earings. The arrangement of the feed and direction of flow of the oil is the same as in Fig. 3. The screw cap 14 is dispensed Within this instance as the driving whirl upon the member 2 has a bearing u on the base and serves to close the oil cham er therein.

It will be observed that a spindle constructed in accordance with my invention as above described may be made up largely of parts stamped, pressed, or spun up from and its support.

11. A spinning spindle comprising a supporting case provided with an oil chamber, a rotatable driven member, a main bearing upon which said member is mounted in suspended relation, a helical oil carrier leading from said chamber to the main bearing, and a downhold for the rotatable member serving as a closure for the oil chamber in the supporting case.

12. A spinning spindle comprising a supporting case having'an oil chamber formed therein, a rotatable driven member provided with a terminal flange lying within the oil chamber, a main bearing upon which said member is mounted in suspended relation, a downhold engaging the terminal flange and serving as a closure for the oil chamber, and means for feeding oil from said chamber to the bearings.
